Abstract

The method of excavation tunnels, as infernal object depends primarily on the rock mass along the tunnel route, as well as rock mass in the nearby environment of the route. This paper presents a methodology for determining the drilling - blasting parameters in one of the various zones along the route of the tunnel. Furthermore, proposed here are the construction of a tunnel in three sections, pattern of the boreholes at the face, as well as the construction charged cut holes, auxiliary and contour blasting holes.
